Sensor Connection
The sensor is connected to the two pin header J8 located at the bottom of the power board as
shown in
Figure 2 . The exact sensor type is determined by the controller configuration. The
sensor cable should not be routed near power carrying wires to minimize noise pick-up.
Power Line Connection
The controller’s operating power is connected at the three ¼” quick connect tabs located on the
left hand edge of the main ECB as shown in
Figure 2 . Beware that traces and components in the
area shown crosshatched in Figure 2 can have potentially lethal voltages to ground and each
other while the unit is under power.
If one leg of the power supply is grounded (i.e. neutral for domestic applications) it should be
connected to the power tab marked ‘NEUT’, since the ‘HOT’ terminal is the fused input.
